Summary
The LIGHT-COG study is a 76-week, multicenter, randomized, double-blind, placebo-controlled, parallel-group clinical trial. A total of 420 type 2 diabetes patients with early dementia are randomized 1:1 to either the active treatment group (receiving subcutaneous injections of mazdutide weekly, with stepwise dose escalation to a maintenance dose per protocol) or the placebo group (receiving matched placebo injections). The primary objective is to evaluate the potential disease-modifying effects of mazdutide on cognitive dysfunction in type 2 diabetes.

Interventions
Mazdutide injection (pre-filled auto-injector pen) is administered subcutaneously at the same time each week. The starting dose is 2.0 mg administered once weekly (QW). Based on individual patient tolerance, the dose should be gradually increased to the target therapeutic dose of 4.0 mg QW over a period of 4 to 12 weeks. The protocol permits adaptive dose escalation up to 6.0 mg weekly when clinically indicated. For participants unable to tolerate dose increases, treatment continue at their maximum tolerated dose. The total intervention duration is 76 weeks.
